TO ALL WHOM IT MAY oonehnn.

Bev it known thatI, C. D. MOODY, of the city and county of StfLouis, and State of Missouri, have invented a new Device for Braking and Starting Cars; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consists in the application to the axle of a car, of aspiral spring, coiled around the axle, and so operated as to be wound up by the application of the'brako-rods and certain other mechanical arrangements, which will be hereinafter more fully described, and a portion of the power that will be exerted to stop the car will thus be stored up in the said spiral spring, and may be used to assist in startingthe car again after the brake-rods shall have been released.

To enable those skilled in the art to make and use my improved apparatus, I will proceed to describe itsoonstr'uetionfand operation.

Figure of the drawings is a plan of the said braking-device.

I Figure 2 is a sectional elevation of it. i 1

The axle A is to lie firmly secured to the wheels A, as usual. There is a loose wheel, '13, on the axle A, between the wheels A, and a spiral spring, O, coiled around the said axle, one end of the springheing fastened to the oar-frame and the other end of it to the wheel B.- There is also on the same axle another wheel, B, of the same size and form as the wheel B; both of these wheels being. mitre-geared friction or corrugated wheels. Thef'wheel B is arranged loosely on the axle A, so it may receive a longitudinal sliding motion on the said axle; and, for the purpose of imparting to the wheel this sliding motion, it is provided with a lever, E, which lever is operated in the same manner as any common brake. Therefore the details eiitare not shown. The wheel B is turned with the axis A by means of a tongue, Z), attached to the axle, and projcotinginto a suitable groove out in the Wheel to receive There is a short axle, D, placed across the axle A, between the wheels 13 and ll, and it should be perforated so as to allow the axle ,1 to pass through it. This short axle D will only have a. sliding motion on the axle A, and it will have on cachet its ends a srnall bevel-wheel, D'. When the lever If! is thrown Q V 80 to Slide h Wheel 13 up against the wheels D, the said wheel 13, as it revolves with the axle A, will, through the medium of the wheels D, transmit a rotary motion to thewheel B in the opposite direction to themotion of the Mile, and, as one end of the spring 0 is attached to this wheel, as has already been stated, the spring 6 will be wound up tightly around the axle A. The wheels D, like those marked 13 and B, may be simply friction-wheels, or they may be corrugated. There is a ratchet, a, on the axle A, into which the pawl a, on.

the wheel B, takes hold, so as to take up the slack at the spring C, while it is being wound up around the axle, and this ratchet and pawlwill enable the spring to act upon the axle, so as to turn it when the lever E releases the friction-wheels B and D from the wheel 13, and so assist in starting the car. As soon as the force of the spring O is spent, asmall spring (not shown) will throw the pawl out of its ratchet, so the car may he hacked or run in the opposite direction, Thepawl afiwill be thrown down into its ratchet by a spring, (not shown,) so as to act simultaneously with the action of the friction-wheels B, B, and D. A similar device to the one 7 already described will be placed on each end of the car, the only difference being the direction in which the teeth of the ratchets are set on the axle and the spring wound around it. The apparatus onou end of the car will he used while the car is going in one direction, and that on the other whilo'it is going in the opposite direction. y l

Having described my invention, what I claim, isi The combination and arrangement of the wheels 13, B, and D, with the axle A, and the spring 0,:1s described c; D. MOODY.
